Tin Stabilizer B is a Methyl Tin Mercaptide Heat Stabilizer. It is currently the plastic heat stabilizer with the most excellent performance for the rolling, extrusion, and injection molding of hard PVC such as transparent fake materials, plate materials and heat contracting membranes. Due to its high safety, it is especially applicable to food packing and other hand PVC products so as to replace other plastic heat stabilizers that have high toxicity. Because its stability is much better than other organic tin stabilizers like Octyl tin stabilizer. So it has been widely welcomed by many large-scale PVC-processing enterprises becoming the key adjuvant in the processing of hard PVC.
